GCP MQL: Rename a line in monitoring chart

Question

I have a simple Google Cloud Monitoring Query Language to show the count of all requests to all containers in kubernetes from log-based metrics. The query is below.

k8s_container::logging.googleapis.com/user/service-api-gateway-prod-request-in-count | sum

The widget will look like below

I would like to rename the long label for the line chart to something shorter like "request count". How do I do it?

Answer 1

So the best I can do is to add a new column to the table and map the column.

In my example, I add add [p: 'error count'] | map [p] to the line, and become like this.

k8s_container::logging.googleapis.com/user/service-api-gateway-prod-request-in-count | sum | add [p: 'error count'] | map [p]

This works in my case.

Answer 2

You can try renaming the value column with | value [request_count: val()].
